Skyline GTR, ridden in every generation (apart from the 35!) they are great, the dream is very much still alive.
Most of you will find this sad but I wanted a colt for years, no real reason I just liked the look of the one owned by a guy who lived near my school, now I have a range-topping one and i'm very happy with it.
Also not technically a car i've always wanted but all of a sudden M3 CSL's seem very appealing.
